The provider named (gidania, Jürgen Kuhse) is regarded in the collector scene as highly reliable; one can trust his statements. The price named for a 146 from the 1980s is fair and appropriate. If the pen, however, is intended as a gift for a beginner, it is recommended to buy a new 146 with full warranty and nib selection, since vintage pieces with specialist retailers do not entail the same service.
